3. DESCRIPTION AND GENERAL TEST REQUIRENIENTS 3.1 Introduction. The tests spedfied in this document are part of the program to design and certify the SBWR. The IC system and the PCC system perform vital roles in removing heat from the reactor vessel and the containment during certain postulated operating and accident conditions.

Full-scale, prototypical condensers for these systems are to be tested at full pressure, temperature and flow conditions. The test facilities specified for this program are not representative of the SBWR systems of which these condensers will be a part. The specified tests are component " Design i

Qualification Tests" tests and therefore the test system performance is not intended nor expected to l be representative of the SBWR system performance.

3.2 Test Objectives- Passive Containment Cooling Condenser. The general objectives of the full-scale PCC test are as stated in the following paragraphs. The specific objectives described in Paragraph 5.1.1 provide additional details to the general objectives.

3.2.1 Thermal-Hvdraulic. Confirm that the Ansaldo designed PCC meets the thermal-hydraulic I

performance requirements for use in the SBWR. Performance requirements are specified in

! Reference f. of Paragraph 2.1.

3.2.2 Structural. Confirm that the mechanical design of the Ansaldo PCC is adequate to assure the structural integrity of the unit for the expected SBWR lifetime process senice conditions.

l 3.3 Test Objectives -Isolation Condenser Tests. The general objectives of the full-scale IC test are l as stated in the following paragraphs. The specific objectives of Paragraph 6.1.1 provide additional l details to the general objectives.

3.3.1 Thermal-Hydraulic. Confirm that the Ansaldo designed IC meets the thermal-hydraulic  ;

performance requirements for use in the SBWR. Performance requirements are specified in j Reference b. of Paragraph 2.1.

1 3.3.2 Structural. Confirm that the mechanical design of the Ansaldo IC is adequate to assure the I structural integrity of the condenser for the SBWR lifetime process senice conditions expected )

between In Senice Inspections.

)

l 3.3.3 In Service Inspection. Confirm the adequacy of proposed In Senice Inspection (ISI) procedures and methods by performing NDE tests prior to testing and after thermal-hydraulic testing has been completed. (Test Requestor will provide NDE tesdng ofIC.)

3.3.4 I cak Detection Methods. Record reference data for use in evaluation of proposed methods l for IC system leak / break detection. (See Paragraph 6.1.1.4) 4 3.4 General Strateev and Descriotion of Tests l i

I j 3.4.1 Definitions. This specification uses the following definitions in referring to the various responsibilities related to the PCC and IC tests: l i Test Requestor -The organization requesting the tests and specifying the requirements,i.e. the SBWR Design Team (GE lead).

Test Performer-The organization responsible for the test facility and performance of the tests, i.e. SIET.

Responsible Test Engineer - The engineer, representing the Test Requestor, responsible for supenising the preparations for testing and the test performance. For the PCC and IC tests this ,

is an ENEA engineer.

3.4.2 PCC Tests. A full-scale unit (two modules) of the Ansaldo designed PCC as described by the documents referenced in 2.2.b and 2.2.g will be tested to accomplish the objectives stated in Section 3.1. Most of the testing will be done at near-steady-state conditions covering the range of the process variables required for SBWR. The condenser pool temperature for most tests will be the equilibrium (steady-state) value and the water level in the pool will be maintained at the normal level (full). The inlet (drywell) pressure, the steam flow r2te and the flow rate of noncondensible gases in the inlet steam will be systematically varied. The tests will include sufficient pressure / temperature cycles (five times the number of cycles used for design) to confirm the '

structural integrity.

3.4.3 IC Tests. One-half (single module) of a full-scale unit of the Ansaldo designed IC as described by the documents referenced in 2.2.a and 2.2.e will be tested to accomplish the objectives stated in Section 3.2. The majority of the tests will be slow transients simulating the thermal cycles l defined in the IC design specification. It is planned to perform 1/3 of the expected lifetime thermal l cycles. At the conclusion of the testing the condenser will be inspected, using the normal ISI procedures, to confirm that there is no excessive deformation, crack initiation or excessive crack growth rate.

Periods of steady-state operation at various conditions will be used to confirm the adequate capacity of the condenser and verify the expected thermal hydraulic characteristics.

l 4.1.3.2 PCC Pool Tank. The PCC pool tank shall be a rectangular elevated tank, open to the '

atmosphere for the purpose of containing the PCC and the water which cools it. The tank shall be J covered, and shall have an opening of 2 m2 (21.5 ft2 ) in the wall,250 mm (9.8 in) above the pool ,

normal water level, for boil-off. The tank shall be large enough and have provisions for internally l attaching, with prototypical mounting hardware, a complete full-scale two-module PCC unit, and l prototypical inlet, vent and condensate drain piping. The pool depth shall be sufficient to i submerge the PCC to a prototypical water level. The required dimensions of the pool are shown in Figure 4 2.

Systems shall be provided to fill the pool with highly purified water prior to a test, to control the tank level and replace boil-off during a test, and to drain the pool for maintenance or modifications to the PCC. The makeup water system shall be sufficient to maintain a constant poollevel at the maximum condensation rate for a period of at least 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />. Pool boil-off (no moisture carrvover) with 15 MWth heat transfer was calculated to be approximately 6.9x10-3 m3/s (110 gpm). The makeup water shall be the same quality as the pool water. It shall be distributed in the pool such that nonprototypical flow patterns and temperature distributions are avoided.

The water quality requirements for the PCC pool tank are shown in Table 4-5.

4.1.3.3 Condensate Drain Tank. A tank shall be provided for collecting the water condensed and drained from the PCC. The condensate drain tank shall be a closed tank, normally pressurized above atmospheric and partially filled with water. The elevation between the PCC pool tank bottom and the condensate drain tank water level shall be adjustable between 2.0m (6.6ft) and 3.5m (11.5ft). The condensate from the PCC shall discharge to the drain tank beneath the water level. A line shall be provided to drain water from the tank during a test to maintain the water level at a controlled position. The tank and drain shall be sized such that flooding of the tank is prevented and good control of water level can be maintained during testing with the greatest expected l condensate flow rate. The condensate flow rate for 15 MWth heat transfer at 689 kPa gage (100 psig) steam inlet pressure was calculated to be 8.2x10-3 m3/s (130 gpm).

The condensate drain tank shall be provided with systems to fill the tank to a predetermined level.

l and to control that level during a test at a constant value by adjusting the rate of tank drain. The tank gas-space during testing shall be maintained at the same pressure as the PCC inlet flow. The l l method of equalizing pressure with the PCC inlet shall not divert flow from the PCC inlet line. l Figure 4-1 shows one method of controlling condensate tank pressure by injecting high pressure air l l into the tank and using a pressure control valve on the gas outlet line, l t

l Venting of the gas space in the tank may be necessary for pressure control or if noncondensible gas is carried into the PCC drain.

4.1.3.4 Noncondensible Vent Tank. Noncondensible gases, separated in the PCC shall be vented to a closed tank. The elevation of the highest expected water levelin the vent tank should be lower than the lowest expected water levelin the condensate drain tank. At some conditions the flow into l

the vent tank may include uncondensed steam, noncondensible gases and liquid condensate carried over from the PCC lower plenum. The vent line from the PCC shall terminate in the vent tank. The vent line discharge in the tank shall be arranged such that testing may be performed wuh discharge either submerged, as in SBWR or unsubmerged. Provision shall be made to drain water

')3A6999 REV 2 s11 NO. I1 from the bottom of the vent tank and to condense steam which may pass through the PCC vent i without condensing.

4 The vent tank shall be provided with systems to fill the tank to a predetermined level, and to maintain that level during a test. Provision shall be made to measure water flow rate from the vent i tank drain, in the event that condensate from the PCC is carried over in the vent line.

j The vent tank gas discharge pipe shall be provided with a system to control the tank pressure by 1

throttling vent tank exhaust. During tests with no noncondensible inlet flow to the PCC it may be l 4 necessary to pressurize the vent tank by some means such as injecting air direcdy into the vent tank l

• i as suggested by Figure 4-1. Although the system is shown to control vent tank pressure, the variable used for setting up the desired test conditions will be PCC inlet pressure.

j 4.1.3.5 Piping. The piping for the inlet gases, condensate drain and venting shall be as pro:otypical as is practical with respect to inside diameter, irreversible hydraulic losses and elevation differences.

The piping external to the PCC pool shall be thermally insulated as necessary to:

1. Minimize the heat losses to the surroundings

2. Ensure an accurate measure of the condensing capacity of the PCC.

Routing shall avoid nonprototypical opportunities for steam pocketing. The vent line shall include a gate valve or flanges for a blind orifice to provide capability to physically prevent venting of the PCC.

4.1.4 Instrument Reauirements (PCC) 4.1.4.1 General Reauirements. All test instrumentation shall be provided by the Test Performer and shall be calibrated against standards traceable to the U. S. National Institute of Standards and Technology or equivalent.

4.1.4.2 Thermal-Hvdraulic. The required thermal-hydraulic measurements, the required accuracy and the proposed digital sampling frequency for the PCC are listed in Table 4-1. The required accuracy in Table 4-1, is given as the "two standard deviation" level of a normally disuibuted error, i.e. there is a 95% probability that the error does not exceed the specified value.

Inside and outside tube wall temperature measurements are required on four tubes at nine axial positions on each tube. The preferred tubes for these measurements are 1A,4A,5Qand 8Q. The location of these tubes in the tube bundle is illustrated in Figure 4-3.The axial locations of the measurements are shown below:

GE Nuclear Energy 23A6999 SH NO. 12

' REV 2 4.1.4.3 Structural. The required structural measurements for the PCC are listed in Table 4-2 and the numbered instrument positions identified in Figure 4-4. The positions are only indicative: the exact locations will be defined by Ansaldo after the stress analysis. See Reference 2.2.c. The two PCC condenser modules are referred to as "A" and "B". Module B is instrumented in only a few positions for comparison with Module A and for confirmation of symmetrical performance. The types of structural measurement required for the PCC are acceleration, displacement, strain, permanent strain and surface temperature.

Acceleration measurements will be made primarily for the purpose of evaluating vibration characteristics and detection of possible condensation / water hammer loads. Piezoelectric accelerometers are recommended for these measurements. The required temperature range is 10 to 177 C (50 to 350 F). The unfiltered signals shall be recorded in analog form with a recorder having a bandwidth of 1 - 500 Hz.

1.inear displacement measurements are required at points specified in Table 4-2 with an accuracy of 0.2 mm (0.008 in).

Total strain on the surface shall be determined at the locations and directions specified in Table 4-2. In general, monodirectional strain gages should be used to determine the total strain. At some positions referred to in Table 4-2, multiple measurements are specified at the same position.

All strain gages shall be compensated for temperature variations in the range of 10 to 177 C (50 to 350 F) and shall be waterproof.

Permanent strain shall be measured at the locations and directions specified in Table 4-2, by surface scribe marks. The distance between scribe marks will be measured prior of testing, once during the test and at the end of the tests, to determine if there has been any permanent strain.

PCC external surface temperatures shall be measured at the locations shown in Table 4-2 and Figure +4 with an accuracy (2 std. dev.) of 3 C (5 F) or better. The temperature range is 10 to 177 C (50 to 350 F).

4.2 Facility Reauirements for the IC 4.2.1 Princioal Functions and Components. A schematic diagram illustrating the essential features of the facility required for testing the IC is shown in Figure 4-5. The principal components of the test facility shall be:

Simulated reactor pressure vessel (RPV).

Steam supply.

Supply of high pressure noncondensible gas (es).

IC pool tank.

Piping and valves.

The test facility must supply steam, water and noncondensible gases in quantities and at conditions which are representative of those anticipated for the SBWR IC.

23A6999 sH No. 20 REV 2 4.2.2 Test Variables. The independent test variables are:

Drain valve position (open or closed).

IC inlet steam pressure.

Noncondensible gas inlet flow rate.

Composition of noncondensible gas.

The following variables shall be controlled:

IC pool tank level (supply makeup to maintain constant level).

IC pool tank temperature.

IC pool water quality.

Steam supply vessel water level.

4.2.3 Comoonent Reouirements 4.2.3.1 Steam and Noncondensible Gases. Saturated dry steam (quality greater than 99.8%) shall be supplied to the IC at a controllable pressure in the range 0.48 to 9.48 51Pa gage (70 to 1375 psig). Available continuous steam flow rate shall be at least 14.3 kg/s (31.6 lb/s) at 8.618 N1Pa gage (1250 psig) (based on 20 htWth).

Provision shall be made for injection of noncondensible gases (nitrogen or air and helium) into the IC steam supply at a controlled and measured rate. The noncondensible gases will be injected at l steam pressures in the range 0.48 to 8.618 hiPa gage (70 to 1250 psig). The gas supplies shall be sized such that the Isolation Condenser can be filled with the gas at 8.618 N1Pa gage (1250 psig) in approximately 30 minutes.

The possible need to provide the capability to heat the noncondensible gases or the gas / steam mixture shall be considered.

4.2.3.2 IC Pool Tank. The IC pool tank shall be a rectangular elevated tank, open to the atmosphere, for the purpose of containing the IC and the water which cools it. The tank shall be large enough and have provision for internally attaching, with prototypical mounting hardware. a full-scale, single-module IC test unit (one-half of a full unit), and prototypical inlet, vent and l condensate drain piping. The upper steam header and upper steam pipe transition fitting shall be I fixed so as to prevent sliding in the horizontal direction to simulate worst case support conditions.

The pool depth shall be sufficient to submerge the IC to a prototypical water level. The required dimensions for the IC test pool are shown on Figure 4-6. The pool shall be covered, and shall have an open area for venting pool boiloff. The open area of the ven: shall be 1 m2 (10.8 ft2),

The IC Pool Tank shall be provided with systems to fill the pool with highly purified water prior to a L test, to replace boiloff and maintain constant water level and temperature during a test. Systems i shall be provided to cool the pool inventory between tests and to drain the pool for maintenance or modifications to the IC. The water quality requirements for the IC pool are shown in Table 4-5.

i GE Nuclear Energy 93A6999 su.No. 21 REV 2

{

] The makeup water system shall be sufficient to replace pool boiloff and water entrained with the

steam and to maintain a constant poollevel at the maximum condensation rate for a period of at l least 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />. Pool boiloff (no carrTover) with 20 NIWth heat transfer was calculated to be approximatelv 9.3x10-3 m 3/s (147 gpm). The makeup water shall be the same quality as the pool water. It shall be distributed in the pool such that non prototypical flow patterns and temperature

distributions are avoided.

The pool cooling system shall provide for control of pool heatup and cooldown rates npical of

SBWR to adequately simulate the design thermal cycles.

~I 4.2.3.3 Simulated RPV. A pressure vessel shall be provided to simulate the reactor pressure vessel (RPV) and supply saturated steam to the IC. The vessel shall be partially filled with saturated water and the steam supply to the IC shall be taken from above the water level and the condensate from i the IC shall be returned to the vessel below the water level. The vessel shall be heated with a source t

sufficient to maintain vessel pressure with maximum heat rejection by the IC.

i 4.2.3.4 Pipine and Valves. The piping for the IC inlet steam, condensate drain and venting shall be

as protonpical as is practical with respect to inside diameter, irreversible hydraulic losses and 1 elevation differences. The piping shall be thermally insulated and routing shall avoid nonprototypical opportunities for steam pocketing.

) The condensate drain line shall have a valve for startup of the IC. The valve shall meet the leakage j (through the valve) and opening time requirements of SBWR IC valve (see document reference in 1 Paragraph 2.1 h.) A valve size as small as 102mm (4-inch) may be used provided the total IC loop l irreversible hydraulic losses (piping, elbows, valves and condenser) do not exceed 6.3 psi at the r maximum flow rate (Reference document 2.1 a, note 5). The valve and operator shall be mpplied by SIET. The condensate drain line shallinclude a loop seal of at least 0.5 m (20 inches) elevation at the return - the simulated RPV.

The condensate drain line shall have a bypass line around the drain valve. The bvpass line shall 1 include a small valve (approximately 20mm ( 3/4-inch]) for simulating drain valve leakage.

The steam supply pipe and the condensate return pipe shall be designed to produce a stress in bending which corresponds to the maximum allowable pipe bending stress of 1.5 Sm which is caused by combined mechanical, seismic, and thermal expansion loads at 8.618 NIPa gage (1250 psig),302 C (575 F). Direction of deflection shall be selected to maximize the resultant ,

stress on the piping and nozzles between the transition fittings and headers. l As an alternative, guides or lugs may be provided at the lower end of these pipes, at locations to be I defined by Ansaldo. If this alternative is selected, the Test Performer shall define the load and moment on the steam supply and condensate drain pipe connections that results from the test facility piping arrangement.

4.2.3.5 Vent Lines. Vent lines shall be provided on the IC from both the upper and lower plenum Each line shall be manually controlled by a normally-closed, fail-closed solenoid valve and shall h.n c a 12.7 mm (1/2-inch) flow restricting orifice to limit the venting rate as in SBWR. Provision shall be made for measuring the volume of gas vented from the IC.

GE Nuclear Energy

' 23A6999 SH No. 22 REV 2 I

It is expected that noncondensible gases injected into the inlet steam will separate in the IC and eventually fill the upper and/or lower IC plenum, and reduce the heat removal capability. The vent l lines shall be used, as described in Paragraph 6.2.1, during tests to remove the noncondensible gases from the IC and restore capacity. The vent lines shall be actuated by manual opening of the solenoid valves. It is desired to manually simulate the automatic venting scheme of the SBWR IC system during some tests (See Reference document 2.1.c.).

1 4.2.3.6 Elbow Flow Nieters. Two horizontal elbows in both the steam supply line and the  !

condensate drain line shall be equipped for use as elbow flow meters. These devices represent the elbow meters used in the SB%R IC system and are not intended to be used for flow measurement in the IC tests. For the SBhR IC system, the elbow flow meters will provide a signal to indicate the occurrence of a break in the IC inlet or condensate drain lines. Their purpose in the SIET test is to provide a measurement of the "lC startup transient" operating signal and noise levels.

One elbow on each of the two lines shall be the same pipe diameter as used in the SBWR IC and the other shall have approximately half of the flow area of the SBWR IC elbow meters. Ninety-degree, long radius (R/d = 1.5), elbows shall be used and the pressure taps shall be in the outer and inner circumferences of the elbow midplane,45 degrees from the inlet end. The pressure tap holes shall be 6 mm (0.236 in) in diameter. There must be no burrs, wire edges or other irregularities on the inside of the pipe at the nipple connection or along the edge of the hole through the pipe wall.

The diameter of the hole should not decrease within a distance of 12 mm (0.472 in) from the inner surface of the pipe but may be increased within a lesser distance.

1 Where the pressure hole breaks through the inner surface of the pipe there must be no roughness, burrs nor wire edge. The edge of the hole may be left truly square or may be dulled (rounded) very slightly.

Connections to the pressure holes should be made by nipples, couplings, or adapters welded to the outside of the pipe. It is important that no part of any such fitting projects beyond the inner surface of the pipe.

It is desirable that the velocity profile of the fluid stream entering the elbow be fairly uniform and free of swirls. The recommendations of the document referenced in Paragraph 2.3.b regarding straight lengths of pipe upstream and downstream of the elbows shall be followed as much as possible. Condensation pots shall be used on the pressure tap lines if necessarf to keep the line full of water.

4.2.4 Instrumentation Reauirements (IC) 4.2.4.1 General Reauirements. All test instrumentation shall be provided by the Test Performer l and shall be calibrated against standards traceable to the U. S. NationalInstitute of Standards and Technology or equivalent.

4.2.4.2 Thermal-Hvdraulic. The required thermal hydraulic measurements, the required accuract and the proposed digital sampling frequency for the IC are listed in Table 4-3. The required accuracy in Table 4-3, is given as the "two standard deviation" level of "normally" distributed error, i.e. there is a 95% probability that the error does not exceed the specified value.

GE Nuclear Enorgy 23A6999 su No. 23 REV 2 1

Temperature, steam flow, condensate tiow and pressure instruments shall be provided to monitor the heatup and cooldown rates of the coolant and the heat transfer from the condenser during the thermal cycle conditions to be tested.

Temperature measurements shall be made on the vertical section of steam pipe which connects to the steam header below pool water level. The purpose of this measurement is to detect condensate return valve or IC unit leakage when the IC is in the hot standby (fully pressurized) non-operating mode with the condensate return valves closed. Six temperature elements shall be located on the outside of the steam pipe spaced at 0.lm (3.9-inch). The upper element shall be at the pool normal water level elevation.

4.2.4.3 Structural. The required structural measurements for the IC are listed in Table 4-4 and the numbered instrument positions identified in Figure 4-7. The positions are only indicative: the exact l locations will be defined by Amaldo after the stress analysis of the IC. See reference 2.2.c. The t pes  !

of structural measurement required for the IC are acceleration, displacement, strain, surface l temperature and surface scribe marks for measurement of permanent strain.

l l

Acceleration measurements will be made primarily for the purpose of evaluating vibration characteristics and detection of possible condensation / water hammer loads. Piezoelectric l accelerometers are recommended for these measurements. The required temperature range is 10 l i to 314'C (50 to 598 F).

I Linear displacement measurement is required at points specified in Table 4-4 with an accuracy of l

+0.2 mm (0.008 in).

Total strain on the surface shall be determined at the locations and directions specified in Table 4-4. In general, monodirectional strain gage should be used to determine the total strain. At some positions referred to in Table 4-4, multiple measurements are specified at the same position. All strain gages shall be compensated for temperature variations in the range of 10 to 314 C (50 to 598 F) and shall be waterproof.

IC external surface temperatures shall be measured at the locations shown in Table 4-4 and Figure 4-7 with an accuracy (2 std. dev.) of 3*C (5 F) or better.The temperature range is 10 to 314*C (50 to 598 F).

l Permanent strain shall be measured at the locations and directions specified in Table 4-4, by surface scribe marks. The distance between scribe marks will be measured prior of testing, once during the test and at the end of the tests, to determine if there has been any permanent strain.

4.3 Data Recording Requirements (PCC and IC Tests) l

! 4.3.1 Data Acquisition. A digital data acquisition system, of adequate capacity to monitor and record all specified measurements, shall be supplied by the Test Performer. The measurements shall be recorded, in digital format, on magnetic tape or diak for later calculation and analysis of test results. Sampling frequency for each measurement shall be adjustable. Preliminaq sampling i frequency requirements are shown on Tables 4-1 through 4-4, but values may be changed prior to testing.

a. Confirm that the stress levels 2t critical locations on the PCC do not exceed design values for j 1

the following conditions:

l

i. Standby operation at normal containment pressure, temperature, gas content and relative humidity.

ii. Pneumatic leak testing.

iii. Transition from operation at normal containment conditions to LOCA and severe accident conditions.

b. Confirm that cyclic loads at criticallocations on the PCC, resulting from flow and/or condensa-tion induced vibration, do not exceed design values during expected periods of PCC operation.

c. Demonstrate, by performing 5 times the expected number of pressure and thermal cycles that the PCC will successfully sunive 60 years of SBWR senice.

5.2 PCC Test Strateev. The PCC tests will be a series of steady-state tests at specified steam flow rate, noncondensible flow rate, inlet gas temperature and inlet pressure (equivalent to dnwell).

The condensate tank pressure will be equal to the inlet pressure and the vent tank pressure will be adjusted to obtain the specified PCC inlet pressure. The PCC pool will be maintained at a constant level (full) and equilibrium bulk average temperature during most tests. The PCC will be brought to the specified conditions and allowed to stabilize, i.e. reach a condition of steady-state heat l transfer and allowed to operate for approximately 15 minutes at these conditions. Data will be recorded during pool heatup and for the period of steady operation.

After successful completion of these tests, one PCC module will be removed from the facility and l

the pool baffled to reduce the effective size. The single module PCC will be tested at conditions equivalent to some of the full PCC tests. The purpose of these tests is to accomplish the ob.jective of Paragraph 5.1.1.3. Tests using helium and helium / air mixtures will also be done with the single module.

The types of PCC tests which are considered to be necessary to achieve the objectives in Paragraph 5.1.1 are listed in Paragraph 5.2.1. Each of these test types is described in more detailin Paragraphs 5.2.2 through 5.2.9. It should be noted that the procedures described in the paragraphs are l proposals and not requirements. The Test Performer may elect to use alternative or modified procedures which accomplish the same objective. The actual test procedures will be part of the l Test Plan and Procedures document described in Paragraph 3.6.

Dennition: A.3.1. Simulated LOCA Pressurizations l The design basis is two LOCAs during the sixty year design life of the PCC. For the test.10 simulated LOCA cycles must be performed. l General Test Procedure: i The PCC is to be rapidly pressurized with saturated steam to 379 kPa(g) (55 psig) and 151:C (303'F). The vent tank discharge valve must be partly open during pressurization to purge air from the PCC tubes and permit heating. The total time period for the pressurization and data recording is approximately 30 minutes. The flow rate of steam required to achieve these conditions can be determined either by shakedown testing or from previously run two-module tests. If the steam supply is not large enough to maintain the required pressure with a steam-only inlet flow to the PCC. air Gow can be added. Pre-adjustment of the vent tank discharge valve position by " trial and error" may be necessarv.

Indeoendent Variables:

1. Pool level - maintain constant at normal level (full).

2. Pool temperature - start with pool at ambient temperature and allow to heat up in response to PCC performance.

3. Inlet gas temperature - adjust to saturated temperature at 379 kPa (g) (55 psig).

4. Inlet steam flow rate - to be determined.

5. Inlet air flow rate - no air flow for these tests unless it is required to achieve the final required pressure.

Test Conditions:

This procedure is to be performed a total of 10 times. The pressurization transient for the PCC must meet the following requirements:

' Close off the inlet, vent and condensate lines as necessan to permit pressurization with air to 758 kPa(g) (110 psig). Pressurize with air to the required pressure, hold pressure for approximately

l-2 minutes and release pressure. The unit may be partially filled with water to reduce the time required for pressurizing. The PCC should be checked for leaks by verifying the absence of air bubbles in the pool approximately once for each fifty cycles.

5.3 Data Processine/Analvsis General Reauirements. The processing and analysis of the recorded test data shall be done by the Test Performer in three steps which are described as " quick look",

" preview" and " full processing and analysis". Equipment and software necessary for the specified data processing shall be provided by the Test Performer.

The Test Performer shall prepare a plan for verification of the accuracy of all data acquisition and data reduction software. This plan shall be approved by the Test Requestor and verification shall be completed by the Test Performer prior to the start of testing.

The objective of the " quick look"is to provide all of the information needed to proceed with the preparation for the next test. This shall consist primarily of verification that the objectives of the test run were achieved, identification of any instruments which may have failed or performed incorrectly during the test, and reviewing structural data to insure the integrity of the condenser for the next test.

The " preview" phase has the purposes of providing representative results from the most significant measurements to be used in the " Apparent Test Results" report, specified in Section 3.7.2, and to aid in defining the details of the remainder of the analysis. It may be that the most convenient way to do this analysis is interactively with the data reduction computer. Time history plots of key parameters shall be prepared and examined to determine time periods of significant interest for  :

more detailed analysis. Summary plots and digital data tables of typical performance shall be prepared. Time periods and parameters of most significance shall be selected for processing during the " full processing and analysis" phase. The " preview" is expected to be completed within 2 to 4 days following the test.

The plots and tables for the Final Test Report, specified in Section 3.7.2, will be generated during the " full processing and analysis" phase to be completed within approximately two months after the test. The purpose of this phase is to organize the data in a form that provides an integrated

3. Three tests as follows:

inject air and vent from the bottom vent inject air and vent from the top vent first then bottom vent inject air / helium mixture and vent from top vent first then bottom vent.

Begin venting all tests at 7.653 MPag (1110 psig) or when pressure peaks.

6. Total number of cycles for test conditions 1 through 16 shall be 45. Number of cycles of Test Condition 16 can be adjusted to maintain this totalif other conditions are repeated, added or deleted.

7. For one test, after time T2, continue to run at pressure P2 without pool refill until pool level decreases to mid-height of condenser tubes.

8. This test cycle should be done at the end of the test series.

9. On the first cycle (or very early in the test), determine system heat losses at pressure P1 and temperatures in the IC inlet pipe with the condensate drain valve closed. Then open the condensate drain valve bypass line slightly and record heat losses and temperature distribution.

Repeat by further opening the bypass line valve and recording data until there is little change in IC inlet pipe temperature.
